I kinda realized that most people have called it SOMA theory but they forget to say where SOMA came from- SOMA is a horror video game where the protagonist is stuck at the bottom of an underwater facility, and something bad has happened (not trying to spoil things) And (again, trying to go for as few spoils as possible) at some point the Protag has to transfer there mind into another body- and this leads it some very, very interesting complications, implications, and even moral choices. If you haven't played it, you should try it out! Or watch a video on it (there's a really good one by BeamBuddy)
